SPECIFICATION forming part of Letters Patent No. 365,220, dated June 21, 1887.

Application filed January 22, 1886. Serial No. 189,804.

To all whom it may concern:

Be it known that I, EDUARD ZICKWOLFF, a subject of the Emperor of Germany, residing at Saarbriicken, Germany, have invented new and useful Improvements in Heat- Regulators, of which the following is a specification.

The object of my invention is to provide a new and improved regulator which automatically regulates the amount of heat admitted to a room, either keeping the temperature of the room constant or raising the same periodically.

The invention consists of an apparatus in which a volatile liquid vaporizing at the ordinary temperature is used, the vapors of which, as they expand under a higher tcmperature, act upon a column of mercury,which operates a device for opening and closing the inlet-valve for the heat, and also of a device for raising the temperature periodically.

The invention also consists of parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a front elevation, partly in section, of my improved regulator. Fig. 2 is a side elevation of the same. Fig. 3 is a sectional plan view on the line a: 00, Fig. 1. Figs. 4, 5, 6, 7, 8, and 9 are detail views, hereinafter more fully described.

The vapors or gases of a volatile liquid which vaporizes at an ordinary temperature expand when subjected to a higher temperature. In my improved apparatus I employ this principle in such a manner that when the volatile liquid, A, confined in a closed vessel, 0, upon a body of mercury, B, vaporizes and the temperature of the air surrounding the vessel 0 increases, the vapors or gases exert their pressure upon the mercury, l3, and force the same into a tube, D, which is fitted into the vessel 0 and extends nearly to the bottom of the same, and in which tube D the pipe E slides.

(No model.)

The pipe E supports and opens into the chamber F, which slides between stationary guides H H, and is counterbalanced byaweight, J. In the chamber F is placed a float, G, provided on its' top with an upwardly-extending arm, G, which connects with a single-armed lever, L, (see Fig. 3,) fulcrnmed on the shaft L, mounted in suitable bearings, L secured to the top of the chamber T.

On the shaft L is fixed a doublearmed lever, M, which is provided on one end with a counterweight, N, and on the other end carries a pulley, b. A similar pulley, c, is placed beneath the pulley b on the chamber F. Around these pulleys b and c is passed a cord, 0, fastened at its upper end to the guide II at a, and at its lower end attached to a lever, d. The lever (l is provided with a toothed segment, cl, which meshes with the pinion d on the valve (1 in the hot-air pipe 17;.

A vertical shaft, K, revolves in suitable bearings attached to one guide H, and is provided with stops I, I, 1*, and I placed suitable distanccs apart and adjustable thereon by means of set-screws or other suitable means. The distances between the stops are greater or less, according to the desired increase of temperature. At the upper end of the shaft K is mounted the Worm-wheel P, which is in gear with the worm S, mounted on a shaft, S, placed in suitable bearings attached to the guide H.

Above the worm-wheel P is placed and keyed to the shalt K a ratchctwheel, Q, with which a pawl, e, engages, which pawl is pivoted to the worm-wheel l, as clearly shown in Fig. 8, so that a revolution of the worm S transmits motion to the shaft K by means of the Worm-wheel P, carrying the pawl c, which engages with the ratchet-wheel Q. One end of the worm S is prolonged to form a drum, T, which is rotated by a cord and weight, B.

On the shalt S is fixed a disk, U, and at the side of the same is placed an eccentric, V. The disk U is provided with a notch, U, in front of which is placed a lever, 72, provided with a lug, g, which prevents the revolution of the disk U with the worm S and the drum T on the shaft S. The said lever h is firmly connected with a second lever, i, so as to form asingle bent lever, pivoted at k. At the front end of the lever 7b is mounted a third lever, Z,

having a lug, m, which rests upon a support, W. The lever Z is held upright by a spring on the lever h, as shown in Fig. 6. X is an hour-wheel of a clock, (see Fig. 7,) provided W113i; projecting pins adapted to engage thelever The operation is as follows: The chamber F having been adjusted to the desired degree-of heat required, now if an increase of temperature takes place, the mercury, B, enters the chamber F and raises the float G, which, by means of the connections G and L, causes the other end of the double lever M, carrying the pulley b, to swing downward inthe direction of the arrow at, whereby the lever cl will close the valve d and prevent the passage of more perature is desired,one of the stops, I, is placed must be placed farther apart.

over a projection on the chamber F at the de sired point indicated on the scale fixed on the guides H, and the other stops, 1, I, and I, are placed above the first stop at definite intervals, according to the desired increase of temperature, so that when a slight increase of temperature is desired the stops I, I 1, and I must be placed nearer together, and when a greater increase of temperature is desired they As the hourwheel revolves, the .pins projecting therefrom strike against the lever Z,'which is pressed from its support W, so that the lever h falls down, and the lug y is displaced from the notch U in the'disk U. The weight R causes a revolution of the drum T and of the 'worm S, so that the latter transmits a partial revolution to the shaft K,which causes the stop I to move from the lug on the chamber F, which is then drawn upward by the counter-weight J. The partial rotation of the shaft K, before men tioned, places the second stop, I, in position to be engaged by the chamber F, so that the said chamber F is held under the second stop in its ascension until the second partial rotation of the vertical shaft, caused in the man ner before described by the clock, permits the chamber F to rise to the succeeding stop. The levers Z, i, and h, which are displaced by the wheel of the clock, are brought back into their former positions by the eccentric V after each,full revolution of the drum T, the said eccentric pressing against the second lever, z, and thereby lifting the first lever, h, and its connecting-leverl upon the support IV, which prevents the further revolution of the disk U, the worm S, and the drum T. In the progressive ascent of the chamber F, the channel or tube through which the heat enters the space is gradually opened to agreater extentby.

the lever d, and remains in this condition un til the vapors created bythe increased admission of heat cause the mercury to enter the chamber F, thereby regulating the admission of the heat, as before described.

. It will be understood that on the distances between the several stops I, I, 1 and I depends the amount of the increase of the heat, while the successive periods at which the 1ncrease of temperature takes place are depend cut on the disengagement of the lever I, which" at stated intervals by means of the bevel gearwheel 2, attached to the lower end of the shaft K and meshing into the bevel gear-wheel f, placed on the shaft f, which is revolved by the crank -handle 1. By this construction the stops on the said shaft K may be turned in the path of the chamber F by hand.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isp 1. In a heat -regulator, the combination, with a closed vessel for containing mercury and a volatile liquid, and a valveoperating lever, of a chamber communicating with said vessel, a float in the chamber, and means for operating the valve-operating lever by the rise and fall of the float, substantially as herein shown and described.
